you can run your fish finder off the parallel system with your TM, but you may run into interference issues. I have done that before and didn't notice any problems, but some units have, so if anything take it as a precaution that might come up.
I run 3 batteries on my boat...all of them being dual purpose rather than just a cranking battery separate from deep cycle. My cranking battery could not keep up with running two GPS systems (one on console, and a combo gps/depth on bow) along with a depthfinder in the back (wife likes it). So...when I replaced I purchased a similar battery to the front ones, then ran two 8 gauge wires to set up a parallel 12v system, yet use a 2 bank charger and a 24 volt TM. Gives me longer running time, and the ability to run the electronics and TM all day without worry of running down batteries for the most part.
